The present invention includes a method for excluding patients from the need for further analysis of Alzheimer's Disease comprising: obtaining a blood or serum sample from a patient in a primary care setting; determining the expression levels of at least 4 of the following proteins: FABP, beta 2 microglobulin, PPY, soluble tumor necrosis factor receptor 1 (sTNFR1), CRP, VCAM-1, thrombopoietin, α2 macroglobulin, eotaxin 3, tumor necrosis factor-alpha (TNF-α), tenascin C (TNC), IL-5, IL-6, IL-7, IL-10, IL-18, 1309, Factor VII, thymus and activation-regulated chemokine (TARC), serum amyloid A (SAA), and intercellular cell-adhesion molecule-1 (ICAM-1); comparing the level of expression from the sample with a statistically locked-down, multi-ethnic, broad age spectrum statistical sample; and determining if the patient is excluded from further testing for Alzheimer's Disease, thereby eliminating the need for further testing of the patient.
